"WEB-FOLDING MACHINE.

Application filed November 29, 1913.

l b all whom it may concern Be it known that I, CONSTANT T. CUN- BALL, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in VVeb-Folding Machines, of which the following is a specification.

The object of this invention is to provide manual means for controlling the speed of one or more of the web feed rolls of the web feeding mechanism so that all of the web sections may be driven at the desired speeds to insure the proper association of the web sections, without interfering with the operation of the machine.

A practical embodiment of my invention is represented in the accompanying draw ings, in which Figure 1 is a section through so much of a web folding machine as will give a clear understanding of the invention, Fig. 2 is a view in front elevation of the same, and Fig. 3 is an enlarged detail section showing the manual means for controlling the speed of the web feed roll.

Two wide webs 1 are shown as passing over the slitting roll 2 where they are separated into a plurality of superposed web sections by the slitters 3. The plurality of superposed web sections are then passed around the single turners 4 and as they leave the points of the said turners the superposed web sections pass between the pairs of rolls 5, 6. The superposed web sections then pass around a plurality of feed rolls 7 on their way to the pair of rolls 8, 9, where they are associated. In the present instance, I have shown two of these intermediate feed rolls 7 acting upon each pairof superposed web sections as it passes from the pair of rolls 5, (3, to the pair of rolls 8, 9.

Upper and lower cross shafts 10, 11, are' suitably mounted in the machine frame. The cross shaft 11 is driven at a certain speed from the vertical drive shaft 12 through the bevel gears 13, 141-, cross shaft 15, and bevel gears 16, 17 The upper cross shaft 10 is driven from the cross shaft 11 through the spur gears 18, 19, 20. The pairs of rolls, 5, 6, are driven from the drive shaft 12 through the bevel gears 21, 22, cross shaft 23 and sets of bevel gears 24, 25, and spur gears 26, 27. The slitting Specification of Letters Patent.

Serial No. 803,734.

roll 2 is driven from the cross shaft 23 through the train of gears 28, 29, 30, 31, 32, The shaft 3% of the slitters 8 is driven from the shaft 85 of the slitter roll 2 through the gears 36, 37.

A friction drive is interposed between each of the web feed rolls 7 and its shaft 10 or 11, which friction drive is under manual control for controlling the speed of each web feed roll. I will proceed to describe one of these manually controlled friction drives, it being understood that the others are similar in construction and operation. A friction disk 38 is keyed to the shaft of the web feed roll 7 and a friction wheel 39 is slidably keyed to its shaft 10 or 11 with its periphery in engagement with the face of the disk 88. A yoke is pivoted at 40 on the main frame and has one arm i1 engaged with a circumferential groove 42 in the hub 43 of the friction driving wheel. The other arm of said yoke is connected to an adjusting screw 45 mounted in a suitable bracket L6 projecting from the main frame. This adjusting screw is preferably provided with a knurled thumb piece 47 for facilitating the manual adjustment of the screw; By turning the screw 45 the yoke will be rocked and the friction driving wheel 39 thereby moved inwardly or outwardly across the face of the disk 38 thus increasing or diminishing the rotative speed of the web feed roll to the utmost accuracy. By this means, the speed of each web section maybe accelerated or retarded so as to bring all of the web sections into exact register at the assembling rolls 8, 9, this being accomplished without interfering in any way with the main drive of the machine.

"While I have shown and described the feeding and slitting of two wide webs into a plurality of superposed. web sections, it is to be understood that the invention may be used in connection with one or more wide webs and sections slit therefrom.

What I claim is 1. WVeb feeding mechanism including means for feeding a plurality of web sections, associating means therefor, web feed rolls for said sections and manual means for independently varying the speeds of said rolls to insure the proper feeding of the web sections to their associating means.

2. Web feeding mechanism including means for feeding a plurality of web sections,-'associating means therefor, web feed rolls for said sections, friction drives for said rolls and manual means for independmeans for independently adjusting the driving Wheels across their disks to vary the speeds of the Web feed rolls for insuring the proper feeding of the Web sections.

4. Web feeding mechanism including means for feeding a plurality of web sections, associating means therefor, Web feed rolls for said sections, friction disks carried by said rolls, cross shafts having friction driving Wheels for said disk'sand manual meansfor independently adjusting the drivyokes.

5. l/Veb feeding mechanism including a 1 suitable frame, means for feeding a plurality of Web sections, associating means therefor,'Web feed rolls for said sections, friction disks carried by said rolls, a cross shaft having friction driving wheels for Copies otthis patent may be obtained for said disks and manual means for independently ad usting the (lllVlllg wheels across their disks to vary the speeds of the web feed rolls for insuring the proper feeding of the web sections, said driving wheel adjusting means including movable yokes mounted on the frame engaging the wheels and ad justing screws carried by the frame engaging said yokes.
